Angelina Jolie and Brad Pitt ended months of speculation that the couple is expecting another child after showing off the "Mr. & Mrs. Smith" star's baby bump Saturday night at the Film Independent's Spirit Awards in California.
They are "thrilled to be adding to their brood," People magazine quotes a source close to the couple as saying. "They are very, very happy."
Jolie walked the blue carpet Saturday in form-fitting black dress that accentuated her growing belly.
The Jolie-Pitt family includes three adopted children and one biological child.
